Bind without specifying options.
Send this message to the akka.io.Udp.UdpExt#manager in order to bind to the given local port (or an automatically assigned one if the port number is zero).
Send this message to the akka.io.Udp.UdpExt#manager in order to bind to the given local port (or an automatically assigned one if the port number is zero). The listener actor for the newly bound port will reply with a Bound message, or the manager will reply with a CommandFailed message.
Default NoAck instance which is used when no acknowledgment information is explicitly provided.
Default NoAck instance which is used when no acknowledgment information is
explicitly provided. Its “token” is null
.
Each Send can optionally request a positive acknowledgment to be sent to the commanding actor.
Each Send can optionally request a positive acknowledgment to be sent to the commanding actor. If such notification is not desired the akka.io.Udp.Send#ack must be set to an instance of this class. The token contained within can be used to recognize which write failed when receiving a CommandFailed message.
This message must be sent to the listener actor to re-enable reading from the socket after a akka.io.Udp.SuspendReading command.
The same as send(payload, target, noAck())
.
This message is understood by the “simple sender” which can be obtained by sending the SimpleSender query to the akka.io.Udp.UdpExt#manager as well as by the listener actors which are created in response to Bind.
This message is understood by the “simple sender” which can be obtained by
sending the SimpleSender query to the akka.io.Udp.UdpExt#manager as well as by
the listener actors which are created in response to Bind. It will send
the given payload data as one UDP datagram to the given target address. The
UDP actor will respond with CommandFailed if the send could not be
enqueued to the O/S kernel because the send buffer was full. If the given
ack
is not of type NoAck the UDP actor will reply with the given
object as soon as the datagram has been successfully enqueued to the O/S
kernel.
The sending UDP socket’s address belongs to the “simple sender” which does not handle inbound datagrams and sends from an ephemeral port; therefore sending using this mechanism is not suitable if replies are expected, use Bind in that case.
Retrieve a simple sender without specifying options.
Retrieve a reference to a “simple sender” actor of the UDP extension.
Retrieve a reference to a “simple sender” actor of the UDP extension. The newly created “simple sender” will reply with the SimpleSenderReady notification.
The “simple sender” is a convenient service for being able to send datagrams when the originating address is meaningless, i.e. when no reply is expected.
The “simple sender” will not stop itself, you will have to send it a akka.actor.PoisonPill when you want to close the socket.
Send this message to a listener actor (which sent a Bound message) to have it stop reading datagrams from the network.
Send this message to a listener actor (which sent a Bound message) to have it stop reading datagrams from the network. If the O/S kernel’s receive buffer runs full then subsequent datagrams will be silently discarded. Re-enable reading from the socket using the akka.io.Udp.ResumeReading command.
Send this message to the listener actor that previously sent a Bound message in order to close the listening socket.
